The Only Necessary Thing Is Strength is the 120th online chapter of One-Punch Man, set during the Monster Association Arc. Genos delivers the rescued Waganma to safety, learns that Saitama is already inside the enemy base, and rejects Hero Association orders before pressing on alone.
Summary
Genos guides the battered support squad and Waganma toward territory held by the Hero Association, cutting through several monsters along the route. As the wounded fighters receive treatment, Sekingar tends to his own injury and rings Sitch to confirm that the boy has been recovered. He then hands the phone across to Genos, who exchanges a few words with Sitch. The commander offers his thanks, apologizes for excluding the cyborg from the opening plan of attack, and starts to ask a favor of him.
Key Events
A flashback shows Drive Knight carrying Nyan's body away for study. Nyan, it turns out, is still alive, and the creature speaks of a fighter able to fell Monster Association executives in a single blow. From this Genos deduces that Saitama is inside the base, clashing with the enemy. He tells Sitch flatly that he will take no orders from the Hero Association and cuts the call. Genos then leaves Waganma in Food Battler Futoshi's care and readies himself to storm the hideout, while Sekingar passes him intelligence on the Monster Association supplied by Drive Knight.
